Detecting Depression: A 1-Minute EEG Test Reveals Mood Shifts

Depression, a challenging condition to diagnose early, may now be detected more promptly using a simple 1-minute Electroencephalogram (EEG) test at home.

Electroencephalogram (EEG) is a test that easily measures electrical activity, and the equipment is relatively inexpensive, such that it may be used to promote the early detection and treatment of depression.

Here we report that some brainwave activities involving phase resetting reflect the depressed mood at the time, which can be easily monitored by measuring the resting EEG with eyes closed for 1 min with a few electrodes.

We instructed 10 participants (nine healthy and one diagnosed with depression, aged 18–34) to record their EEG for 14–26 days. We found that indicators of depressed mood were correlated with the occurrence frequency of EEG phase resetting.
